NKK Switches High Security Keylock CKL12BTW01-035

The CKL series is a high-security keylock with a 19mm bushing, available in flat or tubular key styles, rated for 3A at 250V AC resistive load. It has a contact resistance of 20 milliohms maximum, insulation resistance of 1,000 megohms minimum at 500V DC, and dielectric strength of 1,500V AC between contacts and case. The mechanical life is 30,000 cycles minimum and electrical life is 10,000 cycles minimum. The housing is zinc alloy with chrome plating, the base is LCP, and terminals are copper with silver plating. Operating temperature range is -25°C to +70°C. The switch has a 90° angular throw for two-position operation and a break-before-make contact timing. Mounting torque is 1.5 Nm maximum. Vibration tolerance is up to 55Hz with 0.7mm peak-to-peak amplitude, and shock resistance is 30G in six directions. An epoxy seal protects terminals from contaminants.
